Step-by-step explanation:
One fish eats = 4 pellets
Second fish eats = 5 pellets
No of days one fish stays with Sophie = 72 ÷ 4 = 18 days
No of days second fish stays with Sophie = 72 ÷ 5 = 14.4 days
22,189 - 16,789 = 5400....so she drove/rode 5400 miles in 15 days
5400/15 = 360 miles per day <==
Answer:
8.6 × 10^5
Step-by-step explanation:
New Jersey 8th graders = 920,000
Rhode island 8th graders = 60,000
Difference in Rhode island 8th graders and New Jersey 8th graders population
= 920,000 - 60,000
= 860,000
Answer in scientific notation
860,000
The decimal point will move 5 places in
= 8.6 × 10^5
It form a right triangle
legnth of ladder is hypotonuse
bottom of ladder from wall distance is one leg
distance up wall is other leg
a^2+b^2=c^2
c=hypotonuse and a and b are legs
4^2+b^2=20^2
16+b^2=400
minus 16 both sides
b^2=384
sqrt both sides
b=8√6 ft
aprox
b=19.59ft from ground
